According to The Hollywood Reporter, Hahn will play a character named Ursula in what is described as a "funny, scene-stealing" role.

The sci-fi adventure's story has been described by Disney as the meeting of "a bright, optimistic teen bursting with scientific curiosity" and a "former boy-genius inventor jaded by disillusionment", with the latter role filled by Clooney.

Together, the characters "embark on a danger-filled mission to unearth the secrets of an enigmatic place somewhere in time and space that exists in their collective memory as Tomorrowland".
